Internet Explorer 无法在 Selenium 的无头模式下工作 [使用 headless_ie_selenium]

Question

I am aware that IE does not support headless. But there's a workaround of using virtual desktops on Windows to get it done. This is what https://github.com/kybu/headless-selenium-for-win is doing, but I seem to be running into an issue here.

My IEDriverServer.exe is added to $PATH$, and headless_ie_selenium.exe is also in the same directory as the IEDriverServer.exe

I'm trying to use it like this:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

browser = webdriver.Ie('C:\IEDriverServer_Win32_3.150.1\headless_ie_selenium.exe')

browser.get('www.someurl.com')

I'm pasting the traceback below

Answer 1

The only thing that worked for me was to programatically minimise the IE window on launch, and switch to another virtual desktop while the job runs.

Setting introduce_flakiness_by_ignoring_security_domains helped bypass the "Protected Mode" and "Zoom Level" errors.
